Whether or not anything is conscious has, by definition, no observable effect to anything else. Therefore, everything is "maybe" conscious, although "maybe" isn't exactly the right word. There are infinite different ways you can imagine being something else with the consciousness and capacity for sensations you have, which don't involve the thing doing anything it's not already. Or, you can believe everything and everyone else has no consciousness, and you won't mis-predict anything (unless you assume people don't react to being called unconscious...).
Is AI conscious? I believe "yes", but in a different way than humans, and in a way that somehow means I don't think anyone who believes "no" is wrong. Is AI smart? Yes in some ways: chess algorithms are smart in some ways, AI is smarter in more, and in many ways AI is still dumber than most humans. How does that relate to morality? Morality is a feeling, so when an AI makes me feel bad for it I'll try to help it, and when an AI makes a significant amount of people feel bad for it there will be significant support for it.

Edit: I'm wrong. I could have sworn it said that the groups had similar all-cause mortality, but it doesn't.
